Translation to Kanji

Hey guys,

I'm in need of some translation of the words "Lost Codes" into kanji characters.
I've tried google translator but i'm almost certains theres way too much characters for just a two words.

Well, some words in Japanese cannot be written in "kanji" alone (some words may be written only in hiragana, only in katakana, only in kanji, or in any combination).

When you say "code," do you mean something like cryptogram/encrypted text? Or just a code number? That would already determine what word(s) we might use, which would further determine what writing might be most suitable.

Already the word "lost" would be "ushinawareta" which is most often written with kanji + hiragana combination: 失われた
For example, the book title "Lost World" is 失われた　世界 (ushinawareta sekai).

However, for the movie title, the Japanese version adopted the English title itself, only turned it into katakana writing (most often used for imported words) and went ロスト・ワールド ("rosuto waarudo").
